Michiaki Takahashi

Michiaki Takahashi (高橋 理明) was a Japanese virologist, best known for inventing the first chickenpox vaccine. He developed the "Oka" vaccine by producing v-Oka, a live-attenuated virus strain of varicella zoster virus.

Life
Born at Higashisumiyoshi-ku, Osaka, Japan, on February 17, 1928, Takahashi earned his MD in 1954 from Osaka University's Medical School, and completed in 1959 the Graduate Course of Medical Science, majoring in poxvirus virology.

Between 1963 and 1965 he studied at Baylor College of Medicine in Texas, and at the Fels Research Institute of Temple University, in Philadelphia.

The experience of watching his eldest son, Teruyuki, suffer from chickenpox while studying in the U.S. led him to begin development of a chickenpox vaccine in 1971. The research was extremely difficult, but was completed in 1973. In 1984, the vaccine was certified by the WHO as the most suitable chickenpox vaccine, and in 1986, the Japanese Ministry of Health and Welfare approved it for practical use in countries around the world.

Takahashi became the director of Osaka University's Microbial Disease Study Group in 1994. After retirement from Osaka University, he was given the title professor emeritus.

He died on December 16, 2013, from heart failure.
